View Datasheet Manufacturer Site View Pricing & Stock

Fast settling, highly accurate, low power, 8-/16-channel, multiplexed ADC for low bandwidth input signals with integrated input buffers.Integrated precision, 2.5 V, low drift (3.5 ppm/°C), band gap reference and integrated oscillator.Eight flexible setups with configurability for output data rate, digital filter mode, offset/gain error correction, reference selection, buffer enables and more. This per channel configurability extends to the output data rate used for each channel when using sinc5 + sinc1 filter.Sinc5 + sinc1 filter maximizes channel scan rate, and sinc3 filter maximizes resolution and enhanced 50 Hz/60 Hz rejection, with four selectable options to maximize rejection.Integrated diagnostic features, including CRC, register checksum, temperature sensor, crosspoint multiplexer, burnout currents, and GPIOs/GPOs.
